Fixing ice dam/fascia problem with...a silicone bead?
I had severe ice dams this winter, leading to huge icicles, water pouring through the soffits, warped and cracked soffits, and huge stains on the house.
It turns out, the roughly ten-year-old roof was installed with an ice and water shield, but the shield did NOT bridge the gap between the roof and the fascia. With the gutters full of ice, water easily backed up between the shield and the roof deck.
I have to proposals to fix:
1 Rip off bottom three courses of shingles, reinstall ice and water properly, apply new (matching) shingles
2 Run bead of silicone roofing caulk along edge of ice and water shield
Amazingly, I've read some support for approach number 2. #1 sounds more reliable and permanent, but also costs nearly $4K. There isn't the budget to do Rolls-Royce everything here. The attic also needs re-insulation, the house needs painting, and on and on.
Is the silicone bead insane?
